I am still puzzling over the spring loaded disc. Why spring loaded? So whatever it is contacting cannot be damaged? So it can come in contact but not push too hard on things at varying distances? If it's not magnetic then it must push on something or align something.

Also, the ends of the outer tweezers (for lack of a better word) do not have hooks like you would expect for a chip puller. The ends of the inner tweezers have hooks but they might just be there to keep it locked in place. However, they inner ones do look like they are made to slide forward (narrowed for a few mm near end that goes thru the bent piece of the outer ones)
